Benefits of technology

The patent text describes a system that manages the allocation of computer resources called cores. The system tries to allocate these cores efficiently so that they are used as little as possible, which reduces the number of idle cores. This saves computer resources and improves performance.

Problems solved by technology

With respect to apparatuses that constitute the manycore system, partition scheduling of cores for executing an application becomes an issue.

Embodiment Construction

[0028]Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. Embodiments are described below to explain the present disclosure by referring to the figures.

[0029]FIG. 1 illustrates a partition scheduling apparatus 100, according to an example embodiment.

[0030]According to an example embodiment, the partition scheduling apparatus 100 may receive information associated with a priority of an application to be assigned to a partition, including cores and a required minimum number of cores, and may assign, to the application, a partition that includes at least the required minimum number of cores.

[0031]A general priority based scheduling algorithm using a hierarchical bitmap may be employed for the above partition assignment or partition scheduling. More specifically, a partition may be selected based on a priority of an application and a core may be mapped ...

Abstract

An apparatus for performing partition scheduling in a manycore environment. The apparatus may perform partition scheduling based on a priority and in this instance, may perform partition scheduling to minimize the number of idle cores. The apparatus may include a partition queue to manage a partition scheduling event; a partition scheduler including a core map to store hardware information of each of the plurality of cores; and a partition manager to perform partition scheduling with respect to the plurality of cores in response to the partition scheduling event, using the hardware information.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority benefit of Korean Patent Application No. 10-2011-0096815, filed on Sep. 26, 2011, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Field[0003]Example embodiments of the following disclosure relate to a computing system and an operation method of the computing system, and more particularly, to a partition scheduling method for executing an application in a computing system including a manycore processor.[0004]2. Description of the Related Art[0005]Configuring a manycore system by considering performance and power in a variety of devices, such as, a smart phone, a television, a vehicle, and the like, for example, has assimilated into the mainstream market. With respect to apparatuses that constitute the manycore system, partition scheduling of cores for executing an application becomes an issue.[0006]In a manycore processing enviro...
